Improved hole wall roughness and corrosion resistance of U-shaped hole prepared by casting

نویسندگان

چکیده

The corrosion resistance of the cooling channel in water-cooled mold has an important impact on application mold. In this paper, influence experimental temperature roughness and U-shaped channels prepared by casting is analyzed detail. results show that increased from 998 to 1048K; hole wall decreased 83.264 76.287. However, with a further increase temperature. Because low will promote formation micro bulges river ripples wall. gradually increased, it aluminum matrix react carbon fiber, which roughness. performance analysis reasonable beneficial reduce improve channel. When large, ravines rough surface are easy be starting point corrosion. At same time, cause aggregation Si elements at high temperature, also As result, plays role improving

Nonextremal Black Hole Microstates and U-Duality

A six-parameter family of five-dimensional black hole solutions is constructed which are labeled by their mass, two asymptotic scalar fields and three charges. It is shown that the Bekenstein-Hawking entropy is exactly matched, arbitrarily far from extremality, by a simple but mysterious duality-invariant extension of previously derived formulae for the number of D-brane states in string theory.

Organizational Black Hole Theory

There are issues in organizations that require new theoretical formulation. Hence, metaphorical theorizing is used in the study of organizations to interpret them and understand their complexities. In this method, the organization is likened to an entity and one of the key features of that entity is generalized to the organization. It should be borne in mind that most organizational theories ar...

U(n)-monopoles on Kerr Black Hole and Its Entropy *

We describe U(N)-monopoles (N > 1) on Kerr black holes by the parameters of the moduli space of holomorphic vector U(N)-bundles over S with the help of the Grothendieck splitting theorem. For N = 2, 3 we obtain this description in an explicit form as well as the estimates for the corresponding monopole masses. This gives a possibility to adduce some reasonings in favour of existence of both a f...

Improved initial data for black hole collisions

Numerical relativity codes now being developed will evolve initial data representing colliding black holes at a relatively late stage in the collision. The choice of initial data used for code development has been made on the basis of mathematical definitiveness and usefulness for computational implementation. By using the “particle limit” (the limit of an extreme ratio of masses of colliding h...
